Physics
Work Calculator
Compute the mechanical work done when a force moves an object over a distance, optionally considering the angle between force and motion.
Estimate energy transfer when a force moves an object.
Work-energy principle
Work = Force × Distance × cos(θ)
Force and distance must be in compatible units. When no angle is provided the calculator assumes force and motion align (θ = 0).
How to use
- Enter the applied force and displacement distance.
- Add the angle between force and displacement if the push or pull is not aligned.
- Review total work in joules plus converted kilojoules and foot-pounds.
Example
Input: Force = 150 N, Distance = 12 m, Angle = 25°
Output: Work ≈ 1,629 J (≈ 1.63 kJ, ≈ 1,202 ft·lb)

Deep dive & study plan
Work Calculator: Finds mechanical work using force, displacement, and angle. It's built around work, joules, energy, so you can go from a raw question to a checked answer without switching tools.
The math behind it: Force and distance must be in compatible units. When no angle is provided the calculator assumes force and motion align (θ = 0). The core relationship is Work = Force × Distance × cos(θ), shown above the calculator so you can see exactly how your inputs turn into the result.
To use it well: (1) Enter the applied force and displacement distance. (2) Add the angle between force and displacement if the push or pull is not aligned. (3) Review total work in joules plus converted kilojoules and foot-pounds. Keep your units consistent as you go, and re-run a case you already know the answer to — it's the fastest way to catch a typo before it throws off a result you're relying on.
Worked example: entering Force = 150 N, Distance = 12 m, Angle = 25° returns Work ≈ 1,629 J (≈ 1.63 kJ, ≈ 1,202 ft·lb). Try swapping in your own numbers next, especially a case you're unsure about, before you use this for something that matters.
Quick retention checklist
- Speak the formula aloud (or annotate it) so the relationships stick.
- Write each step in your own words and compare with the numbered list above.
- Swap in new numbers for the Example to make sure the calculator (and your logic) handles edge cases.
- Check at least one related calculator below — it's the fastest way to confirm your numbers still line up from a different angle.
FAQ & notes
What if the object doesn’t move?
Set the displacement to zero; the work output will also be zero because no energy transfers when distance is zero.
Can I enter negative angles?
Yes—negative angles reverse the cosine component so the work result reflects opposing force directions.
What formula does the Work Calculator use?
Force and distance must be in compatible units. When no angle is provided the calculator assumes force and motion align (θ = 0).
How do I use the Work Calculator?
Enter the applied force and displacement distance. Add the angle between force and displacement if the push or pull is not aligned. Review total work in joules plus converted kilojoules and foot-pounds.
